Known issue, and so far Avast doesn't have a permentent fix out for this issue, just check Avast offical forum, been dealing with this for weeks now, as well as dealing with Behavior shield not starting

Probably giving up on Avast myself, tired of all the trouble shooting, and such

Trouble shooting/fixing 4 PC's is where I draw the line after so long of dealing with it

There is an workaround reported in Avast forum, but even that reported to not work anymore, i'll post it here in case you wanna try it

Weird thing is that I have done the update on 4 computers now, all running Avast. Two of them did not have a problem. Upgraded to 1803 and Avast ran fine right out of the gate.
One of them had this problem. But I just had to manually disable Windows Defender Real Time Shields, and that solved it on that laptop.
But on this PC it is nasty. Nothing seems to get it going. Yet it runs fine on all the others. Go figure.

Yeah I've had problems on all 4 of my systems, well not so much the 4th one, but all 3 of other ones, Nasty on PC 1, PC 2, Laptop not so much, but still not that great, and 4 System purring right along lol

I had the same issue and uninstalled it but removing Avast caused internet connection issue. Finally I fixed the problem. Now I'm using windows build-in security center and I think it's great, so far so good. My PC is much faster now.

Yeah! That was really weird: the network connection going down after uninstalling Avast. I just restarted the router and it cleared up, but WTF?

There are a LOT of little nagging bugs due to this 1803 upgrade, not just with Avast. Really wish I had waited to do it. I have an image to restore but not pissed off enough to do that yet.

As for AV, my impression is that Windows Defender is alright, but not as good as many free AV we can run (source: any search for "best Free AV"). As best said on Tom's Guide: "Windows Defender is better than Nothing". It's main claim to fame is the fast startup and seamless operation with Windows (Do I smell Internet Explorer and Windows 98?).
But in AV reviews Windows Defender rarely even shows up in a top ten list for effectiveness.

So I am going to try and get Avast to work on this PC. The most recent info on their forum is that they are aware of the problem and are working on getting a hotfix out soon, maybe sometime next week. We should look for a newer version than 18.4.2338. That should have the fix in it.

I'll Probably use Defender for now on Main PC, Keep it on one of the household systems, and when confirmed fixed probably reinstall on Main System possibly. I used Avast since 2003, do trust it, just couldn't stand the UI Failing, behavior shield not loading anymore on main system. Not counting the system file checker corruption issue I had

I only use the minimal AV modules, never any of the add-ons. There are better programs that do things like System File Checker.
I do a Minimal install, sometimes disable Behavior Shield, and add the Mail Shield and the Software Updater (the only add-on that I find useful.)
That way, as a straight-up AV we can avoid most of the problems people report.

It's all we can do right now. Can't go out into the interwebs naked!
So I too will run Defender until it all gets sorted.

Would love to know what change MS made in 1803 that causes this. I've got a feeling it is just some Service or Policy that changed.
I sure the software manufacturers are loving the need to recode every 6 months for what is essentially a new Operating System.

Hi,
